Red Sm:KGd(WO 4 ) 2 laser at 649 nm
We report on the first laser operation of a Sm 3+ -doped monoclinic KGd(WO 4 ) 2 double tungstate crystal in the red spectral range. Pumped by a frequency-doubled optically pumped semiconductor laser (2 ω -OPSL) at 479.1 nm, the 0.8 at. % Sm:KGd(WO 4 ) 2 laser generated an output power up to 17.6 mW...
